Mengshen3-Pack Safety Wedge Door Stop Alarm Stopper Blocking Travel Home Security Alert 120db (Pack of 3) MS-M68

A simple device that does what it says. Even on low sensitivity, it is quick to go off and the alarm is loud, so no chance people won't hear it.

Door alarms which have aloud warning if triggered by the door being opened. It has a switch to switch on and off, and a second switch to choose 3 sensitivity settings. It is so simple to use and solid construction with a gripper to stop it from moving. I think the unit is great value for money

Alarm is quite loud. Max. Sensitivity setting maybe too much if door rattles with wind, post man, etc. Less sensitive setting avoids nuisance tripping.Negatives; if a door has very little clearance with the floor, i.e., less than 5mm, this door alarm would need something like a credit card laid on top of metal strike plate so that the credit card contacts the floor beneath the door in order to trip.

Light, easy to use, has 3 levels of alarms and works a treat. Used it in London at the hotel and felt safe and secure

Great product and it’s alarm is LOUD will disturb the whole building-hotel

Seems good it but unfortunately it didn't work on my carpet floor.

I take this on all my solo trips abroad and in this country and can sleep well at night knowing no-one can get into my hotel room. Works really well. Once in place, the door can't move at all.

Rec'd TY - Very loud alarm ( which is good!) - Make sure that it is off when you insert the battery!
